the core counts are arbitrary I just think it would be interesting to see how it scales up, if this test is scaling with 99% efficiency that is not so good for bulldozer, but if there is a large decline as cores go up then that could be good news.

I just found this out and have not seen it come up yet in discussion, C-ray measures floating point performance which is bulldozers weak point as it only has one FP unit per module. Integer performance then should be about double which would put it on par with sandy bridge.

Its pretty interesting what AMD has done. Just forget about the number of cores!, they created the bulldozer module which contains 2 integer cores and 1 FP core. A CPU will contain various bulldozer modules.

This redesign is aimed to increase performance on generic programs, which uses lot of integer operations (games included). Programs which makes use of a lot of FP operations (math, video encoders...) would probably not get performance boost.

Indeed, it should be interesting to see more tests of this AMD CPU redesign.

Agreed here. Also, from what I've read (including the usual marketing stuff), the aim of the Fusion line, and likely Bulldozer, is not single threaded performance, or even single program performance. It's multi-program, multi-threaded performance, with lower power usage that they're aiming for.

One still can improve the c-ray performance if one uses opencc as a compiler (http://www.openbenchmarking.org/resu...D1SA-CRAYCOM20). The standard makefile deliverd by PTS isnt aware of the CC env-variable, so i patched the install.sh in ~/.phoronix-test-suite/test-profiles/pts/c-ray-1.0.0/ .
